RAILWAY-RAIL STAY.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed June 16, 1905. Serial No. 265,491.

To all whom it may concern:

Be it known that I, HIRAM H. SPONENBURG,

of W'adsworth, in the county of Lake, in the State of Illinois, have invented new and useful Improvements in Railway-Rail Stays, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to railway-rail stays of that class composed of two jaws which are adapted to grip the flanges of the rail by the action of a bolt connecting the jaws and which are disposed to abut against one side of the cross-tie for the purpose of preventing longitudinal creeping of the rails and resultant throwing of the track out of alinement and gage.

The present invention is an improvement upon the form of rail-stay shown and described in my United States Letters Patent No. 779,104, dated January 3, 1905; and its object is to provide a'rail-stay which shall be more efficient in resisting the creeping movement of the rail and at the same time to produce a construction which shall be simple,

strong and durable, and can be readily applied to the rail, which shall also be inexpensive.

To that end the invention consists in the novel arrangement and combination of the component parts of the rail-stay hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure 1 shows a transverse section of a rail provided with my improved rail-stay. Fig. 2 isa plan View of the same and indicating by an arrow the direction in which the rail tends to creep. Fig. 3 is a vertical section on the dotted line X X in Fig. 1. Fig. a is a transverse section of a rail provided with a modified form of the rail-stay. Fig. 5 is an enlarged detail perspective View of one of the rail-gripping jaws minus the chilled-iron or steel serrated plate. Fig. 6 is an enlarged detail perspective view of said plate, and Fig. 7 is a vertical section on the dotted line Y Y in Fig. 3.

Referring to the said drawings, A represents the well-known T-rail which is supported upon the cross-tie B and spiked thereto in the usual manner.

C denotes a rail-gripping jaw embodying my present invention. Said jaw consists of a block composed of malleable iron or other suitable metal and is formed with an car a and breast Z), projecting at right angles from the opposite side portions thereof, andiwhich are provided with bearing-surfaces by which they grip the bottom of the flange c of the rail A, said breast being disposed to abut against the side of the cross-tie B. The upper portion of said block is formed with an overhanging lip (Z, which is adapted to grip the top of the rail-flange c. The inner face of said lip is disposed at an angle in relation to the gripping-faces on top of ear (6 and breast Z), thereby producing a groove 6 corresponding to and receiving the said railflange. Said inner face of the lip (Z is formed with a recess or pocket f, having undercut or dovetail end walls, as indicated -at'g g.

7a denotes a gripping-plate, which is composed of chilled-iron or steel and is disposed in the said recess f. This plate has its ends beveled, as indicated at i 2', to correspond with the walls g g of the recess and is thus supported in the said recess, and its thickness is greater than the depth of the recess in order that the lower face of this plate shall project below the lip, which face is provided with short slots disposed in pairs, asindicated at 7) b, and to provide the corresponding ends of each of the walls g with similar slots 0.

By providing these slots portions of the edge of the lip (indicated at (Z (Z) may be bent down to form tongues, and the end portions of the walls 9 9 (indicated at e 6') may be bent inward to form like tongues, which tongues serve to lock the plate 72 in the recess, as more clearly shown in Figs. 5 and 7 of the drawings.

The jaw C is provided with a transverse aperture f, which is disposed cent-rally between the car (a and breast b for the reception of a bolt D and which has its top in a plane with the bottom of the rail.

In some instances I prefer to use the form of rail-stay shown in Figs. 1 and 2 of the drawings, in which only one jaw O is employed and is applied to one of the rail-flanges 0 in the manner aforesaid. In this case I use a plain hook-shaped jaw C, which grips the other flange and is formed on one end of a strap or bar g, which extends across the under side of the rail A. The opposite end portion of the strap is formed cylindrical and screw-threaded and constitutes the bolt D, passing through the aforesaid aperturef of the jaw C and provided with a nut 7t, engaging the outer face of the jaw. By tightening the said nut the jaws C C are caused to be firmly clamped to the railflanges and the serrations a a a of the aforesaid plate hbecome embedded in the top of the said flanges. By thus clamping the jaws onto the rail with the breast b abutting against the cross-tie B it is obvious that the stay will ef fectually resist the creeping of the rail. By referring to Fig. 4 of the drawings it will be observed that two of these jaws C C may be employed. In this form of rail-stay I employ an ordinary bolt D, formed with a head 2', engaging the outer face of one jaw, and provided with the nut h, engaging the corresponding face of the other jaw.

If desired, the tongues cl 6 may be dispensed with, thereby rendering the plate It removable.

What I claim is e p 1. The improved rail-stay comprising a jaw abutting againstthe side of the.cross-tie and formed with a groove receiving the rail-flange, a flange-gripping plate confined at the top of saidgroove, and a bolt passing across the un der side of the rail and clamping the jaw onto the rail as set forth. H

p 2. The improved rail-stay comprising a cast-metal jaw abutting against the sideof the cross-tie and formed with a groove receiving the rail-flange, a hard-metal flange-gripping plate confined in the groove and provided with serrations or teeth adapted to embed themselves in the top of the flange, and means for clamping the jaw onto the rail as set forth.

3. The improved rail-stay comprisinga jaw provided with means for clamping the same onto the rail-flange and with means abutting against the side of the cross-tie, said jaw being formed with a surface gripping the bottom of the flange and with an undercut overhanging lip, and a plate confined in said undercut portion and gripping the top of the flange as set forth.

4. A railway-rail stay comprising a jaw abutting against the cross-tie and formed with a groove receiving the rail-flange, a hard-metal flange-gripping plate disposed in the top of the groove, thesaid jaw being provided with bent portions confining the plate in its position, and means clamping the jaw onto the rail as set forth. v Y

5. A rail way-rail stay comprising a jaw c'o nsisting of a block provided with an" aperture and formed with an abutment engaging the cross-tie and with a groove receiving the rail flange, and the top of the groove provided with a recess, a chilled-iron serrated plate disposed in said recess and gripping the top of the flange, tongues formed on the said jaw at the groove and locking the plate in the recess, and a suitably-supported bolt passing across the under side of the rail and extending through the aperture of the jaw and provided with a nut engaging the outer face of the jaw and forcing the jaw onto the rail and causing the'serrations of the aforesaid plate to be embedded in the flange as set forth.

6. A railway-rail stay comprising a jaw consisting of a block formed with a breast projecting at right angles therefrom and abutting against the cross-tie and with a correspondingly-projecting ear, said breast and ear provided with bearings gripping the bottom of the rail-flange and the block provided with a transverse aperture disposed between the breast and ear, an overhanging lip formed on the jaw and provided withau undercut recess, achilled-iron or steel plate confined in said recess and provided with a serrated face gripping the top of the rail-flange, asuitably-sustained bolt passing across the under side of the rail and extending through said aperture, and a nut on th'ebolt and engaging the outer face of the block for the purpose set forth.

'7 railway-rail stay comprising a jaw abutting against the side of the cross-tie and formed with a groove receiving one of the railflanges and provided with a serrated flangegrippingplate confined at the top of the groove,

a suitable jaw gripping the other rail-flange,

anda bolt drawing said jaws into clamping positions as set forth.

8. A railway-rail stay comprising a jaw abutting against the cross-tie and formed with a groove receiving one of the rail-flanges and with a recess in the top of the groove, a chillediron or steel plate disposed in said recess and provided with a serrated face for gripping the top of said flange, a hook-shaped jaw gripping the other rail-flange and abutting against the cross-tie, and a bolt forcing said jaws into clamping positions as set forth.

9. A railway-rail stay comprising a jaw abutting against the side of the cross-tie and formed with a groove receiving one of the railflanges and provided with a serrated hardmetal flange-gripping plate confined at the top of the groove, and a transverse aperture below the groove, a hook-shaped jaw gripping the other rail-flange, a bolt formed integral with the latter jaw and passing across the under side of the rail and through the aforesaid aperture, and a nut (in said bolt and engaging the outer faceof this apertured jaw as and for the purpose set forth;
